Add a real-time verification layer to every coded unit on the line with a date code verification vision system that runs on your existing line cameras, built on vision AI for date and lot code verification. Built for the operations where one no-print event, clogged printhead, or stale date left running after changeover can mean pallets rejected at the retailer's DC, a recall that widens because the lot can't be read, or a finding on a regulated line. Whether you're coding cans and bottles on a filler, pouches and film on a flow wrapper, cartons on a cartoner, or cases at palletizing, Roboflow extends your verification coverage to every unit at line speed, validatable under FDA 21 CFR Part 11 and cGMP.
Date, Lot, and Expiration Code Reading:
- Read inkjet, laser-etched, and thermal-transfer codes on cans, bottles, caps, pouches, film, and cartons, including curved, glossy, and low-contrast surfaces
- Verify code content against the active work order, so the date, lot, and plant code on the package match what the batch record says they should be
- Confirm code placement and orientation so codes land in the printable zone, not across seams, artwork, or perforations
Catch Coding Failures at Line Speed:
- Detect missing and no-code units the moment a printhead clogs, skips, or runs dry
- Flag smudged, faded, and partially printed characters before illegible product reaches the case packer
- Catch wrong-code events after changeovers, where yesterday's date or the previous SKU's lot keeps printing on today's product
Serialization, Traceability, and Line Integration:
- Pair code reading with barcode and GS1 verification for DSCSA serialization and retailer compliance programs
- Tie every verified code to its batch record, shift, and line for tight recall scoping and traceability
- Trigger rejects and line stops in real time through PLC and MES integration, with a per-unit audit trail behind every decision
Bring intelligence to every code today. Stop coding errors from becoming retailer chargebacks, unscoped recalls, or compliance findings.
More About Date and Lot Code Verification
What is date and lot code verification with Vision AI?
Date and lot code verification with vision AI uses computer vision and OCR models (opens in a new tab) to read the date, lot, batch, and expiration codes printed on every unit, and verify the content matches what the active work order says it should be. Models trained on your actual packaging and print conditions check presence, legibility, correctness, and placement at line speed on every unit rather than sampled checks, with per-unit records that support FDA 21 CFR Part 11, cGMP, and FSMA traceability requirements.
What is a date code verification vision system?
A date code verification vision system is a camera and software setup at the coder, labeler, or case packer that reads the date code printed on every unit and checks it against the active work order: present, legible, in the right place, and the right value for today's batch. Roboflow provides the vision system as software that runs on the cameras your line already has or a single added camera, with deep-learning OCR models trained on your packaging and printers, and PLC integration to reject or stop the line when a code is missing or wrong. It covers date codes on their own or date, lot, and expiration codes together, and keeps a per-unit record behind every decision.
Can Vision AI read smudged codes on curved or glossy packaging?
Curved cans, glossy film, condensation, and dot-matrix inkjet are what make code reading hard: characters wrap around radii, glare washes out low-contrast print, and a partially clogged printhead produces codes a fixed-threshold reader gives up on. Deep-learning OCR models trained on your real substrates, your printers, and your line conditions read through distortion, gloss, and partial print, and classify the borderline cases (legible but degrading) so you can catch a failing printhead before it produces a single unreadable unit.
Does date and lot code verification support FSMA and DSCSA?
Yes. Roboflow models can run as documented verification controls that support FSMA (Food Safety Modernization Act) traceability and recall-scoping requirements, DSCSA (Drug Supply Chain Security Act) serialization programs, cGMP batch record accuracy, and FDA 21 CFR Part 11 electronic records, alongside GS1 coding standards for retailer compliance. Roboflow is the verification engine; your quality and regulatory teams own the acceptance criteria, and the platform keeps the per-unit records, model versions, and training data lineage that audits ask for.
Can it integrate with our coding equipment, reject systems, and MES?
Yes. Roboflow Inference (opens in a new tab) exposes a standard API and supports common industrial protocols, so verification events flow into your existing systems: coding and marking equipment from Videojet, Domino, and Markem-Imaje, line PLCs from Allen-Bradley and Siemens, SCADA and HMI platforms like Ignition and AVEVA, MES and ERP systems like SAP and Oracle, through REST (opens in a new tab), MQTT, OPC UA, and direct database writes. PLC-level integration drives rejects, diverts, and line stops the moment a missing or wrong code appears, with a full audit trail behind every decision.
